Inline (180° Adjustment)
Offset (360° Rotation)
Two Mounting Flanges
FEATURES: Adjustable Locking Hubs are rotary bearings that provide
positive locking at any 10° increment. Once locked, the hub becomes an
absolutely rigid joint, able to withstand 80 ft-lbs of torque (5:1
safety factor). Applications include adjustable fixtures, rotating
fixtures, welding fixtures, trunnion mounting, adjustable handles,
foldable handles, adjustable part trays, adjustable shelves, adjustable
racks, adjustable and/or fold-away work surfaces, positive positioning
of lighting or nozzles, and collapsible structures. Patent numbers
5,586,363 and 5,689,999. Other patents pending.
INLINE MODEL: Hub extensions line up in the same plane. Total range of
movement is 180°.
OFFSET MODEL: Hub extensions are offset to allow full 360° rotation.
Offset hubs should usually be used in pairs, to avoid off-center loading
on a single hub and ensure full strength. Make sure that rotating loads
MOUNTING: The version shown here has mounting flanges that provide two
options for mounting: 1) two 1/4-20 tapped holes allow fastening an
object to the mounting flange; 2) two 9/32"-dia clearance holes for 1/4"
or M6 screws allow fastening the mounting flange to a surface.
SAFETY PRECAUTIONS: Avoid any possible pinch points, especially with
heavy loads. Do not release the hub unless adequate support for the load
is in place. Do not let loads swing freely. When using offset hubs that
can rotate 360°, always ensure that loads are balanced in the rotational
